An intramolecular frustrated Lewis pair has been shown to react with different organic azides to form a range of 4, 5 and 6‐membered heterocycles, and the varying reaction paths are rationalized computationally. The product derived from trimethylsilyl azide rapidly extrudes nitrogen, and the resulting cyclized iminophosphorane/borane adduct was explored as a catalyst for the trimerization of isocyanates.
